CNC Machining Stainless steel

Stainless steel is the abbreviation of stainless steel and acid-resistant steel.The steel resistant to air, steam, water, and other weak corrosive mediums is called stainless steel. And medium steel resistant to chemical corrosion medium (acid, alkali, salt, etc.) is called acid-resistant steel.
Stainless steel is widely used in our life, and the shadow of stainless steel products can be seen everywhere. The excellent heat resistance, corrosion resistance, polishing performance and high hardness of stainless steel make it useful in different fields, especially in automobile, aerospace, medical care and consumer electronics.
With rich experience and extensive knowledge, U-Need Precision Machinery
can process custom stainless steel parts and products to high precision tolerance requirements.

Popular Grades of Stainless Steel and their Characteristics

Material Grade	Material properties
201&202	Non-magnetic, high strength, weak corrosion resistance.
301	301 stainless steel shows an evident eork hardening phenomenon during deformation, which is used for a variety of occasions requiring higher strength. Non-magnetic, but magnetic after cold working.
304	304 stainless steel is a universal non-magentic stainless steel with good corrosion resistance, heat resistance, low-temperature strength and mechanical properties; Stamping, bemding, and other hot workability are good, with no heat treatment hardening phenomenon.It is widely used to produce equipment and parts requiring good comprehensive performance.
304L	It is a variant of 304 stainless steel with low carbon content and is used for welding occasions.The lower carbon content minimizes the carbides precipitation in the heat-affected zone near the weld,which may lead to intergranular corrosion (welding corrosion) of staninless steel in some environments. Howevwr, after welding or stress relief, it sresistance to intergranular corrosion is excellent; It can also maintain good corrosion resistance without hea treatment.
316	On the basis of 10Cr18Ni12 steel adding Molybdenum,316 stainless steel has good resistance to reducing medium and pitting corrosion. In seawater and other media, the corrosion resistance is superior to 304 stainless steel,mainly used for pitting corrosion-resistant materials.Non-magnetic,excellent work hardening.
316L	Stainless steel ultra-low carbon steel, with good resistance to sensitized intergranular corrosion, is suitable for manufacturing thick section-size welding parts and equipment, such as anti-corrosion materials in petrochemical equipment
321	Titanium stabilized Austenitic stainless steel, added titanium to improve intergranular corrosion resistance, has good high-temperature mechanical properties and can be replaced by ultra-low carbon austenitic stainless steel. Except for special occasions such as high temperature or anti-hydrogen corrosion,it is generally not recommended to use.
430	As the representative of ferrite steel,403 grade stainless steel has a low thermal expansion rate,excellent formability, and oxidation resistance.
410	As the representative of marteensitic steel, although it has high strength, it is unsuitable for harsh corrosion environments, It has good workability, hardens according to the heat treatment surface hardenging,and is magnetic.
